In fact it appears where you click. If you create a button with 'uisetcolor' as callback, the dialog box appears near the button. And if the button is near the screen borders, the dialog box is not displayed entirely, making it sometimes impossible to move!

BTW, how do you change the uisetcolor preference? I did not manage to find that.

As I mentioned, it may be different for that new colour picker, which I rejected. I created my own colour picker in the end, but I still find it useful to have uisetcolor sometimes which is why I set it to use the old version. It is a hidden preference in code rather than a visible one, as described in a comment to the answer in the linked thread.

Not a direct solution of your problem, but maybe it helps to use one of the alternative color choosers: https://undocumentedmatlab.com/blog/color-selection-components

cc = javax.swing.JColorChooser;
[jColorChooser,container] = javacomponent(cc,[1,1,450,325],gcf);
jColorChooser.getColor

cp = com.mathworks.beans.editors.ColorPicker;
[jColorPicker,container] = javacomponent(cp,[1,1,400,200],gcf);

Or:

options = 0;
icon = 0;
cp = com.mathworks.mlwidgets.graphics.ColorPicker(options,icon,'');
[jColorPicker,hContainer] = javacomponent(cp,[10,220,30,20],gcf);
